One of the biggest concerns for anyone going through a divorce in Ontario is what will happen to their property. How are assets divided? Will you have to sell the family home? What about pensions and investments? Ontario has a specific legal framework for dividing property on marriage breakdown, and understanding it is crucial to protecting your financial future.
Ontario Uses Equalization, Not Equal Division
A common misconception is that everything gets split 50/50 in a divorce. Ontario law does not actually divide property equally between spouses. Instead, it uses a system called equalization of net family property under the Family Law Act. The goal of equalization is to ensure that both spouses share equally in the wealth accumulated during the marriage. This is done through a calculation, not by physically dividing assets.
How the Equalization Calculation Works
Each spouse calculates their net family property (NFP) by taking the value of all assets they own on the date of separation, subtracting all debts and liabilities on the date of separation, and then subtracting the value of property they brought into the marriage (with some exceptions). The spouse with the higher NFP pays the other spouse half the difference. This is called the equalization payment. For example, if Spouse A has an NFP of $500,000 and Spouse B has an NFP of $200,000, the difference is $300,000. Spouse A would owe Spouse B an equalization payment of $150,000.
The Matrimonial Home: Special Rules
The matrimonial home receives special treatment under Ontario law. Unlike other assets, the full value of the matrimonial home on the date of separation is included in the equalization calculation, regardless of when it was acquired or who paid for it. This means that even if one spouse owned the home before the marriage, its value on the date of marriage cannot be deducted. Both spouses have an equal right to possession of the matrimonial home until a court order or separation agreement says otherwise, regardless of whose name is on title.
What Property Is Excluded?
Certain property is excluded from the equalization calculation, including gifts or inheritances received during the marriage (as long as they were kept separate and not mixed with family assets), life insurance proceeds, and property that both spouses agree to exclude through a domestic contract. However, any increase in the value of excluded property during the marriage is included in the calculation.
Pensions and Retirement Savings
Pensions are often one of the most valuable assets in a marriage. In Ontario, the portion of a pension earned during the marriage is subject to equalization. Valuing pensions can be complex and often requires an actuarial valuation. RRSPs, TFSAs, and other registered savings are also included in the equalization calculation at their value on the date of separation.
Common Disputes in Equalization
The equalization process is often more contentious than it appears on paper. Common disputes include disagreements over the valuation date, the value of a business or professional practice, whether an asset qualifies as excluded property, the value of the matrimonial home (especially in a volatile real estate market), and whether one spouse dissipated assets before separation. Each of these issues can significantly affect the equalization payment, and they often require expert evidence such as business valuations, real estate appraisals, or actuarial reports. Understanding these potential flashpoints early in the process helps ensure that nothing is overlooked.
